  1. Re:Remember when.. on Former Intel Engineer Pleads Guilty To Taliban Aid · · Score: 3, Informative
    When there is evidence, then you are guilty.

    No.

    "Innocent until proven guilty" is an addage that is appropriate when there is not any evidence available to support a charge.

    "An adage" is a very peculiar way of describing the Fifth Amendment to the Constitution of the United States, the Supreme Law of the Land.

    It has come time, imho, that combating terrorism has got to involve more prevention than reaction

    The entire modern system of justice rests on the pillar of adjudication. Take that away and you have a mockery.

  2. On any properly implemented system... on Can .NET Really Scale? · · Score: 5, Insightful
    ...the overhead of the framework for your code contributes only a small percentage to the total system load.

    In other words, it's not what you're using to do it, it's how you're doing it. If you're just pumping out files to clients on modems, 100+ concurrent requests isn't much. If those requests are all CPU-bound, I hope they're all niced or set to a low priority, otherwise you won't be able to log into the machine in a reasonable amount of time. If it's 100+ concurrent connections, but those connections aren't necessarily waiting for a response (just idle until the user does something) then you might not even care.

    How many whatevers you have must always be qualified by knowledge of what those whatevers are doing. Otherwise your whatevers won't fit in your $20k thingamajig. And then Mr. Bigglesworth gets upset.

    Of course, whether .NET is a properly-implemented system is a separate debate...

    It was Tex Johnston, one of Boeing's top test pilots, in a 367-80 (a 707 prototype) doing an aileron roll over the hydroplane races at Seattle's Seafair.

    I was told long ago that a 747 is good for 2.5Gs, so it'd be a pretty slow snap roll. Most light aircraft are rated for +6/-3 or so Gs and most acrobatic aircraft are rated for at least +/-9.

  5. Re:Audio quality? on Build a Multi-Output MP3 Server? · · Score: 1
    That depends entirely on the audio-frequency electromagnetic radiation noise floor at the particular place you've run your cable. A/C power lines are something important to avoid - a 60hz hum will be audible with anything other than cheap computer speakers. Generally, don't run your antenna (speaker cables) parallel to other antennas (power infrastructure, phone lines) for extended distances. You may find it worthwhile to twist balanced lines or shield unbalanced lines - and if you absolutely must convert between the two, use baluns.

    I would say these things become a concern at distances of 100 feet or more - 50 if you have bad luck or good ears.

    Attenuation, or how much power goes into heating the wires instead of moving the speakers, is easier to calculate. Your speaker system will have a specified impedance (for home speakers, usually 8 ohms, sometimes 16 ohms) with a DC resistance very near this. Add that resistance to the resistance of your wire (look up the ohms per foot in a wire table) and divide the speaker's resistance by the total (for example, if you have 8 ohm speakers, and your wire resistance was 1.5 ohms, only 8/9.5 or 84% of your power would make it to the speakers).

    Baby Boomer Disease (that's the sickness some of the older guys in my office have, where they fanatically assert that no good music has been produced since the early eighties)

    I've reached the conclusion that most popular music seems to be written to single people. People find ways to relate to music before they get hitched, are no longer able to relate to music they haven't already heard after that point (and no longer have the time to invest in it, either), and are then stuck.

    I just get really angry when some foolio can claim to know anything about philosophy when he spends very little time with it. I mean I can spend hours on 2-3 pages of work trying to figure it out.

    Philosophy is not a math problem. It is not a task. It is not an accomplishment. It is not something to 'do'. It is a love.

    Any 'foolio' can love. Some of them can even love without going on about their level of loving 'expertise'.

  10. Re:NEVs? on Washington State Legalizes NEVs on Public Roads · · Score: 4, Informative
    Oh, and don't forget that according to the 2nd law of thermodynamics, you've lost energy at every step in that process, so you are probably not as efficient as a good gasoline engine

    Assume a power plant is 80% efficient. Assume electricity distribution is 95% efficient. Assume lead-acid columetric efficiency is 70%. Assume larger electric motors are 90% efficient.

    .80*.95*.70*.90 = ~.48

    Your total efficiency still exceeds the brake efficiency of most car engines by several percentage points. Also, car engines lose energy at the clutch and transmission, must waste energy while idling, and cannot recoup energy from braking.

    The assumptions above are from quick google searches - if you have better/conflicting info, let me know.

    But do they convert the other 88% to heat the way that incandescent bulbs convert 90% of the electricity they use into heat with the 10% converted to light as almost a byproduct?

    Like anything else they follow the law of conservation of energy, so yes. BTW, incandescents are more like 3% light, 97% heat. Either way the light portion turns into heat when something absorbs it. Heat is an amazingly dense form of energy storage, so one tends not to notice it so much, but all other energies are slowly turning into it (entropy).
